This is a must-read to understand a man who shaped our reality, many times over. Personal computers. GUIs. Movies. Music. Tablets. Reading. Video games. The impact Steve Jobs has made on our world is inestimable.

Isaacson has dug deep and uncovered loads of information through his interviews. Even from the early years, I learned a few things I didn't know about Jobs. My major impressions from this book, though, are that:

1. Jobs walked a lot.
2. Jobs cried a lot.
3. People who change the world, who achieve greatness as measured by the world, are amazingly callous and narcissistic.

I was also surprised to learn how little of what Apple has accomplished went according to some master plan or overarching strategy. They've made it up as they've gone along, learning from their mistakes and successes, reacting to the market and to technology, and striving always to make what customers really want. It will be interesting to see Apple's future without Jobs.
